SL320 Exterior light malfunction, need help!

I own a 1996 Mercedes-Benz SL32 with 42k miles, after I got done washing it I wanted to go for a cruise and I tried turning on my exterior lights and no lights popped on. Neither head lights or tail lights worked. When I try and use the blinkers the bulbs work and when I hit the brakes my tail light bulbs also work, and my high beams work. The lights just won’t stay on if I try and use the light knob. Any ideas? I checked the fuses and they all looked good to me. When I try and pull out the light knob for my fog lights the little orange light does NOT eliminate. Thank you.

PS- all of my interior lights work just fine as well.
